Inganda zinganda zigaragaza umubyimba ntarengwa ushingiye ku bwoko nubunini bwicyuma, ukemeza ko ishobora kwihanganira ibidukikije igenewe imyaka ibarirwa muri za mirongo.

HDG nubundi buryo: Kugereranya imikorere 2025

Guhitamo sisitemu yo kurinda ruswa bisaba kureba neza imikorere, kuramba, nigiciro kirekire. Mugihe ubundi buryo bwinshi bubaho,gushyuhaburigihe byerekana ko isumba iyo ugereranije neza na marangi, epoxies, na primers.

Kurwanya Irangi na Epoxy

Irangi rya epoxy na epoxy ni firime yo hejuru. Barema urwego rukingira ariko ntiruhuza imiti nicyuma. Iri tandukaniro ryibanze riganisha ku cyuho kinini cyimikorere.

Epoxy coatings ikunda gutsindwa. Barashobora kumenagura no gukuramo, kwerekana ibyuma munsi. Iyo bariyeri imaze gucika, ruswa irashobora gukwirakwira vuba. Ubuyobozi bwa leta ya New York Thruway bwize ibi. Babanje gukoresha epoxy-coated rebar kugirango basane umuhanda, ariko impuzu zacitse vuba. Ibi byatumye imihanda yangirika vuba. Nyuma yo guhindukira kuri rezo yo gusana ikiraro, ibisubizo byarashimishije kuburyo ubu bakoresha ibikoresho bya galvanised mumishinga yabo.

Imipaka yimyenda ya epoxy igaragara neza iyo uyigereranije na HDG.

Gushyira hamwe no kubika nabyo birerekana ibibazo bikomeye kuri epoxy coatings.

• Ibyangiritse: Epoxy iroroshye. Igishushanyo mugihe cyo gutwara cyangwa kwishyiriraho kirashobora gukora ingingo zintege nke zo kwangirika.
• UV Ibyiyumvo: Epoxy isize ibyuma bisaba ibiciro byihariye byo kubika hanze. Igomba kuguma itwikiriwe kugirango irinde kwangirika kwizuba.
• Gutakaza Adhesion: Igipfundikizo c'icyuma gishobora gucika intege mugihe, ndetse no mububiko.
• Ibidukikije byo mu nyanja: Mu bice byo ku nkombe, epoxy coatings irashobora gukora nabi kuruta ibyuma byambaye ubusa. Umunyu nubushuhe byoroshye gukoresha inenge iyo ari yo yose.

Mubidukikije, HDG yerekana kwihangana. No mubice bifite umuyaga wumunyu utaziguye, ibyuma bya galvanis birashobora kumara imyaka 5-7 mbere yo gukenera kubanza kubungabungwa. Ahantu hihishe kumurongo umwe urashobora gukomeza kurindwa imyaka 15-25.

Kurwanya Zinc-Rich Primers

Zinc ikungahaye kuri primers akenshi itangwa nkamazi asimbuye yogusunika. Izi primers zirimo ijanisha ryinshi ryumukungugu wa zinc uvanze muguhuza irangi. Ibice bya zinc bitanga uburinzi bwibitambo, ariko sisitemu yishingikiriza kumurongo wubukanishi, nkibara risanzwe.

Ibishyushye bishyushye, bitandukanye, birema ibice byayo birinda binyuze mu gukwirakwiza ubushyuhe bwinshi. Ibi bikora ibishishwa byukuri bya zinc-fer byahujwe nicyuma. Primer ikungahaye kuri primer gusa ifata hejuru. Iri tandukaniro muguhuza nurufunguzo rwimikorere ya HDG.

Ikiranga	Bishyushye	Zinc-Rich Primer
Urwego	Inkunga ya metallurgical irema zinc-fer iramba.	Umukungugu wa Zinc muri binder utanga uburinzi bwibitambo.
Kwizirika	Yahujwe nicyuma hamwe nimbaraga zingana ~ 3,600 psi.	Imashini ya mashini ishingiye ku isuku yo hejuru; intege nke cyane.
